Learn about Pressure Gauges
Pressure gauges are instruments used to measure pressure. The analog dial pressure gauge, or pressure gage, is the most common and economical gauge. Typical applications include use as a water pressure gauge, air pressure gauge, vacuum gauge and test gauge.
The Wika pressure gauge is a quality instrument used to measure pressure in a large variety of applications. The dial pressure gauge is the most common and economical gauge. Many of the Wika Instrument gauges are Made in America for fast and reliable deliveries.
Pressure Gauge Types
Stainless steel pressure gauges are industrial quality with heavy-duty sensing elements and case designs. These gauges are typically used in more demanding applications. The stainless steel gauge is built for extended life, clean flowing media and harsh corrosive environments.
Industrial quality gauges feature heavy-duty sensing elements, stainless cases, and are typically used in more demanding applications. These gauges usually have greater accuracy requirements over general purpose gauges. The industrial gauge is built for extended life and designed for harsh environments.
Process gauges combine the heavy-duty operating and construction requirements of stainless industrial gauges, with the more exacting accuracy and service life demands of process type applications. Designed for the chemical and petroleum processing industries, the cases are made of corrosion resistant thermoplastic and offer a solid front/blow out back safety case design.
Standard dial type test gauges are cost effective, extremely sensitive and highly accurate. These gauges are excellent for instrument shops, gauge repair and calibration shops, testing laboratories and other applications demanding precision and consistent results. Test gauges feature adjustable knife-edge pointers and mirror bands on the dial to assure precise readings.
Commercial gauges are economical and often referred to as general purpose or equipment gauges. Though commercial gauges may be ruggedly constructed, the service conditions are not expected to be severe. Most commercial gauges are constructed with black ABS or painted steel cases with brass internal parts and connection.
Most low pressure gauges utilize a capsule or diaphragm sensing element and accurately measure pressures less than 15 PSIG. Typical measuring units are inches of water, mm of water, oz/sq inch, and pounds per square inch.
Pressure gauges specially made to measure vacuum or less than atmospheric pressure. The most common units of measure for vacuum pressure are inches of Hg, inches of H2O or the metric equivalents .
